Problems solved by technology

[0002] Due to the concealed life of the stem-boring pests of red maple, a lot of delays in prevention and control are caused. When they are discovered, it is often impossible to re-inject pesticides to save the life of the trees, because most of the larvae are bored into the pith in a curved line on the rhizome. Then the outer ring reaches the epidermis, causing the suspension of nutrient delivery at the gnawed part of the root, causing the tree to wither and die

Embodiment 1

[0017] In late March 2009, in Nanjing City, Jiangsu Province, 2038 red maple trees with a size of 4-10 cm were selected, and the soil was removed at the junction of the rhizomes of the red maple, and the soil layer of 10-15 cm was removed downwards, and then 50% of the soil was used Apply the phoxim stock solution to the bark, and apply about 15 cm to the upper and lower parts of the rhizome. Finally, wrap the place where the lotion is applied with a polyvinyl chloride film and seal it tightly with tape. The incidence of stem borer pests in the treated maple was only 0.6%.

Abstract

The invention discloses a method for preventing and treating red maple trunk-borer insects, comprising the following steps of: pushing away soil on a root-stem juncture of a red maple from the last ten-day period of March to the first ten-day period of April and removing a soil layer with the thickness of 10-15 cm; then coating tree barks by using phoxim basic solution with the concentration of 50% and respectively coating about 15 cm of the basic solution on the root and the stem from the top down; and finally, utilizing a polyvinyl chloride film to cover places coated by the solution and sealing the places by adhesive tapes. The method provided by the invention has the advantages that: firstly, long-horned beetles are prevented from ovulating in cracks of the tree barks of the root and the stem; and secondly, ovulated eggs can be effectively killed so that larvae incubated by the eggs are prevented from entering a tree trunk to cause the tree to die.

Description

technical field [0001] The invention belongs to the field of forest protection, and relates to a method for preventing and treating dry maple pests. Background technique [0002] Due to the concealed life of the stem-boring pests of red maple, a lot of delays in prevention and control are caused. When they are discovered, it is often impossible to re-inject pesticides to save the life of the trees, because most of the larvae are bored into the pith in a curved line on the rhizome. Then the outer ring is bored to the epidermis, causing the suspension of nutrient delivery at the gnawing part of the rhizome and causing the tree to wither and die. The invention blocks the passage of the beetle to lay eggs on the rhizome and the larvae to enter the trunk, so that the death rate of the red maple is greatly reduced. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for preventing and controlling the stem-boring ...
